Intensive Widmannstätten Nanoprecipitates Catalyze SnTe With State‐of‐the‐Art Thermoelectric Performance

open access: yesAdvanced Materials, EarlyView.
The intensive lath‐shaped Ag2Te Widmannstätten nanoprecipitates are in situ generated in SnTe via AgPbSbTe3 alloying, and align with the formation of the parallel type and twin type interfaces. These Widmannstätten nanoprecipitates effectively scatter phonons to reduce the lattice thermal conductivity, resulting in a significantly enhanced average ZT ...

Spin‐State Manipulation of Atomic Manganese Center by Phosphide‐Support Interactions for Enhanced Oxygen Reduction

open access: yesAdvanced Materials, EarlyView.
The electronic configuration of Mn single‐atom sites is regulated from low‐spin to high‐spin states by embedding well‐defined molybdenum phosphide nanocrystals nearby (MoP@MnSAC‐NC). The electronic phosphide‐support interaction between MoP and Mn single atoms drives the electronic structure transition in Mn sites from low‐spin to high‐spin states, and ...

Robust Mix‐Charged Polyzwitterionic Hydrogels for Ultra‐Efficient Atmospheric Water Harvesting and Evaporative Cooling

open access: yesAdvanced Materials, EarlyView.
Conventional atmospheric water‐harvesting hydrogels prioritize hygroscopicity at the expense of mechanics, hindering its practical applications. The proposed hygroscopic mix‐charged polyzwitterionic hydrogel(THMPH) achieves a trade‐off between high water absorption and exceptional mechanical robustness through a strength gradient‐enhanced ionic cross ...
